About the Bank of America Corporate Center
Rising 265 m (871 ft) in Uptown Charlotte, North Carolina, the Bank of America Corporate Center was designed by the Argentine architect César Pelli with HKS Architects. The building is chiefly known as the headquarters of the bank it is named for, and no building in North Carolina has been taller since it was built in 1992. Locals sometimes call it the "Taj McColl", a nickname drawn from Hugh McColl, the bank's former CEO, who was behind the tower's construction.
NCNB chairman Hugh McColl announced Pelli's design on September 25, 1987, and it was unveiled to the public on June 14, 1988. The tower has 60 floors and a 9.1 m (30 ft) granite base. Its facade is rosy beige granite and silver glass, with curved sides, and it tapers through six setbacks to the tip of its crown, 265 m (871 ft) above Tryon Street.
Demolition on the site began on January 3, 1989, and the first concrete pour, on November 19, 1989, marked the start of actual construction. The foundation reaches 12 m (38 ft) below Tryon Street, and 36 concrete and steel piers support the tower. It was topped out on October 2, 1991, and the 29 m (95 ft) crown was finished that December. The lobby holds three frescoes by Ben Long, each 5.5 m by 7.0 m (18 by 23 feet) and called the biggest secular fresco in the U.S.

- A stepped crown
- The tower narrows through a series of setbacks to a small crown. Printing slowly and using layers of 0.12 to 0.16 mm helps keep the steps and the tip crisp.
- Fine vertical ribs
- The face of the tower is covered in narrow vertical ribs. Print friendly adapts them to the print scale; Full detail keeps more of them, which suits a larger print or a fine nozzle.
- Pick the detail for your nozzle
- In the Buildings settings, set Landmark detail to Print friendly to adapt thin parts and small details to the print scale. Full detail keeps every modeled feature, for larger prints or a finer nozzle.
- Colors
- Buildings, roads, water and ground arrive as separate filament slots in the 3MF. The Bank of America Corporate Center takes the building color.
- File format
- You get a 3MF for Bambu Studio, OrcaSlicer or PrusaSlicer. Any of them can save it as STL if you need one.
